Would I have a virus?

Avast! blocked a virus 7 times today.
(I share my computer)
The other person using it got a spam e-mail from someone they believed to be a friend (didn’t check the address to tell, I did and it was spam), and they opened it. They got linked to a doctor’s website about dieting and weight loss, and then left the PC away for upwards of ~6 hours. 7 blocked viruses were attempting to enter, according to the logs. I’m running a scan now, do I have a virus?

to find out, follow instructions https://forum.avast.com/index.php?topic=53253.0
attach Malwarebytes / Farbar Recovery Scan Tool / aswMBR logs

Do I have to run full scans? They crash my computer.

it is explained in instructions … read it all several times before you start so you know what to do

It said nothing about full scans.

First log, MBAM scan.

Will DL other things and follow up with more logs tomorrow.
Can you guys do anything with the MBAM logs?

No… we need Farbar Recovery Scan Tool logs first

Alright. Will do!

Running Farbar.

Chromes been crashing alot for the past few days, would that have anything to do with it?

Run this programme

The Norton is paid for and I don’t know any serial numbers/passcodes for it, so I couldn’t get it things back if it got removed, and the others sharing the computer would likley get angry. Can I do anything else besides remove Norton?

Yes remove Avast, you cannot have two AV’s running on the same computer and expect no problems

Nothings ever happened before.
